Identify the glycolysis intermediate among the following: a. Fructose-1-phosphate b. Fructose-1,6-bisphosphate c. Coenzyme Q d. Sucrose e. None of the above 15. Which of the following enzymes is BOTH present in the glycolysis pathway AND not involved in regulation of the glycolysis pathway? a. Hexokinase b. Phosphofructokinase c. Phosphoglycerate kinase d. Alcohol dehydrogenase e. Pyruvate kinase 16. If you were to isolate ATP synthase in your lab, what other substances would you also need in order to produce ATP using this? a. AMP, inorganic phosphate, electrons, and a lipid membrane b. ADP, inorganic phosphate, and complex IV c. ADP, inorganic phosphate, electrons, and complex IV d. ADP, inorganic phosphate, electrons, and a suitable buffer e. None of the above is sufficient 17. Which of the following terms described the process of ATP synthesis in the electron transport chain? a. Substrate level Phosphorylation b. Photosynthetic Phosphorylation C. Oxidative Phosphorylation d. Reductive Phosphorylation e. None of the above 18. What is the net yield of ATP per glucose that passes through all aerobic respiration (glucose-CO2 and H2O) ? a. 2 b. 3.5 to 5.5 ?. 30 d. 30 to 32 e. None of the aboveExplanation / Answer
12)-option c is correct because in glycolysis there are 10 steps catalysed by 10 enzymes.
13)-option e is correct because it remove phosphate group from ATP.
14)-option b is correct because it is intermediate of glycolysis.
15)-option c is correct because it is not a regulator of glycolysis.
16)-option d is correct.
17)-option c is correct because ETC pathway coupled with oxidative phosphorylation to generate ATP.
18)-option d is correct because from one glucose molecule approximately 32 ATP generate.
